A respiratory mask is reduced in size to better fit patients with smaller faces by either (a) folding one or more accordian folds formed in an upper portion of the mask, or (b) tearing away a part of the upper portion of the mask. The respiratory mask for adult patients can thus be adjusted to fit smaller adults and larger children. The respiratory mask for children can thus be adjusted to fit smaller children. A ball joint swivel connector is provided to connect the gas inlet of the masks to the hose connection for respiratory or nebulizer treating gases or aerosols.

A size-adjustable respiratory mask, comprising:at least one accordian fold formed in an upper portion of the mask; a button or snap associated with the accordian fold; a band defining one or more openings for receiving the button or snap and extending generally along a length of the mask; and a deformable strap bridging the upper portion of the mask, wherein said accordian fold has an open position and a folded position and is held in its folded position when the button or snap in received within one of the openings in the band, wherein the mask can be made smaller to better conform to the facial dimensions of a patient by folding the accordian folds into folded positions that cause the mask to have a smaller length than when the accordian folds are in their open positions, and wherein folding the accordian folds results in substantially linear contraction of the upper portion of the mask. 10. The mask of claim 9, wherein the deformable strap is formed of bendable metal and is bendable to conform to the contours of a patient's nose to hold the mask in place.11. The mask of claim 9, wherein the band has a proximal end and a distal end, and the proximal end is attached to the deformable strap.12. The mask of claim 11, wherein the distal end of the band defines the openings.13. The mask of claim 12, wherein the openings are eyelets.14. A size-adjustable respiratory mask, comprising:at least one strip formed in an upper portion of the mask; wherein said mask can be made smaller to better conform to facial dimensions of a patient by tearing the strip and separating the upper portion of the mask from a lower portion of the mask along a path defined by the strip, and wherein the strip has a proximal end and a distal end and a tear tab is formed at the proximal end. 15. The mask of claim 14, wherein a second tear tab is formed at the distal end.16. A size-adjustable respiratory mask, comprising:at least one strip formed in an upper portion of the mask; wherein said mask can be made smaller to better conform to facial dimensions of a patient by tearing the strip and separating the upper portion of the mask from a lower portion of the mask along a path defined by the strip, and wherein the strip is formed of a material that is more rigid than adjacent material forming the mask. 17. A size-adjustable respiratory mask, comprising:at least one strip formed in an upper portion of the mask; wherein said mask can be made smaller to better conform to facial dimensions of a patient by tearing the strip and separating the upper portion of the mask from a lower portion of the mask along a path defined by the strip, and wherein the mask defines perforations adjacent to the strip such that the strip is rippable away from the remainder of the mask along the perforations. 18. The mask of claim 17, further comprising a plurality of strips formed in the upper portion of the mask.19. The mask of claim 18, wherein the plurality of strips are aligned in parallel.20.
